    SUISUN BAY 139 SUISUN BAY 140 SUISUN BAY SUISUN BAY Located immediately downstream of the confluence of the Sacramento and San Joaquin Rivers, Suisun Bay is the largest contiguous wetland area in the San Francisco Bay region. Suisun Bay is a dynamic, transitional zone between the freshwater input of the Central Valley rivers and the tidal influence of the upper San Francisco Estuary. This area supports a substantial number of nesting herons and egrets, including three of the largest colonies in the region. Although suburban development is rampant along the nearby Interstate 80 corridor to the north, most of the Suisun Bay area is protected from heavy development by the California Department of Fish and Game and a number of private duck clubs.

The Bay Plan was prepared by the Commission over a three-year period pursuant to the McAteer-Petris Act of 1965 which established the Commission as a temporary agency to prepare an enforceable plan to guide the future protection and use of San Francisco Bay and its shoreline. In 1969, the Legislature acted upon the Commission’s recommendations in the Bay Plan and revised the McAteer-Petris Act by designating the Commission as the agency responsible for maintaining and carrying out the provisions of the Act and the Bay Plan for the protection of the Bay and its great natural resources and the development of the Bay and shore- line to their highest potential with a minimum of Bay fill.

  • Field Assessment of Avian Mercury Exposure in the Bay-Delta Ecosystem
    Assessment of Ecological and Human Health Impacts of Mercury in the Bay-Delta Watershed CALFED Bay-Delta Mercury Project Subtask 3B: Field assessment of avian mercury exposure in the Bay-Delta ecosystem. Draft Final Report Submitted to Mark Stephenson Director Marine Pollution Studies labs Department of Fish and Game Moss Landing Marine Labs 7544 Sandholt Rd. Moss Landing, Ca 95039 Submitted by: Dr. Steven Schwarzbach USGS Biological Research Division Western Ecological Research Center 7801 Folsom Blvd. Sacramento California 95826 and Terry Adelsbach US Fish and Wildlife Service Sacramento Fish and Wildlife Office Environmental Contaminants Division 2800 Cottage Way, Sacramento Ca. 95825 1 BACKGROUND The Bay/Delta watershed has a legacy of mercury contamination resulting from mercury mining in the Coast Range and the use of this mercury in the amalgamation method for extraction of gold from stream sediments and placer deposits in the Sierra Nevada. Because mercury, and methylmercury in particular, strongly bioaccumulate in aquatic foodwebs there has been a reasonable speculation that widespread mercury contamination of the bay/delta from historic sources in the watershed could be posing a health threat to piscivorous wildlife. As a result this systematic survey of mercury exposure in aquatic birds was conducted in both San Francisco Bay and the Sacramento/San Joaquin Delta. The Delta component of the survey was subtask 3b of the CalFed mercury project. The San Francisco Bay component of the project was conducted at the behest of the California Regional Water Quality Control Board, Region 2, San Francisco Bay. Results of both projects are reported on here because of overlap in methods and species sampled, the interconnectedness of the Bay/Delta estuary and the need to address avian wildlife risk of mercury in the region as a whole.
